[tex]x-\ number\\\\ 6x+8=4x \ \ \ \ | subtract\ 4x\\\\ 2x+8=0\ \ \ | subtract\ 8\\\\ 2x=-8\ \ \ | divide\ by\ 2\\\\ x=-4\\\\ Number\ is\ -4. [/tex]
the sum of 6 itmes a numbber (6 times x or 6x) and 8 (8) (6x+8) is equal to (=) 5 times the number (5x)

6x+8=5x
subtract 5x form both sides
6x-5x+8=5x-5x
x(6-5)+8=x(5+5)
x(1)+8=x(0)
x+8=0
subtract 8 from both sides
x=-8
